Operators
An operator is a symbol that tells the compiler to perform specific mathematical or
logical functions. C language is rich in built-in operators and provides the following
types of operators −
• Arithmetic Operators
• Relational Operators
• Logical Operators
• Bitwise Operators
• Assignment Operators
• Misc Operators
We will, in this chapter, look into the way each operator works.
Arithmetic Operators
The following table shows all the arithmetic operators supported by the C language.
Assume variable A holds 10 and variable B holds 20 then −
Show Examples
Operator Description Example
+ Adds two operands. A + B = 30
− Subtracts second operand from the first. A − B = -10
* Multiplies both operands. A * B = 200
/ Divides numerator by de-numerator. B/A=2
% Modulus Operator and remainder of after an integer division. B%A=0
++ Increment operator increases the integer value by one. A++ = 11
-- Decrement operator decreases the integer value by one. A-- = 9
, Example 1: Arithmetic Operators
// Working of arithmetic operators
#include <stdio.h>
int main()
{
int a = 9,b = 4, c;
c = a+b;
printf("a+b = %d \n",c);
c = a-b;
printf("a-b = %d \n",c);
c = a*b;
printf("a*b = %d \n",c);
c = a/b;
printf("a/b = %d \n",c);
c = a%b;
printf("Remainder when a divided by b = %d \n",c);
return 0;
}
c = 5
c = 10
c = 5
c = 25
c = 5
c = 0
Relational Operators

variable A holds 10 and variable B holds 20 then −
